Installation height of the heated floor thermostat in the bathroom. Connecting a heated floor to a thermostat (thermostat)

A heated floor is a rather complex, well-functioning system consisting of a heating element, the coolant in which, depending on the type, can be electric current or hot water. The most popular are heated floors powered by electricity. Installation of this type of system involves the installation of not only wires that will give off heat, but also a thermostat. A heated floor sensor is also installed.

The temperature sensor is one of the most important elements included in the floor heating system. This is a copper conductor covered with insulating material; the end of the sensor is covered with a special cap to protect it from various external influences. The principle of operation of the device is simple: the sensor independently determines the floor temperature (when heated, the resistance of the device decreases) and then reports the received information to the thermostat.

Next, the thermostat, depending on the data received - high or low temperature - automatically turns the floor heating system on/off. Typically, the device is triggered if the temperature drops below the set point by only 0.5 degrees. In general, the frequency of the “on-off” cycle depends on several factors - thickness, type of coating, heating temperature in the room, presence or absence of insulation.

On a note! The temperature sensor can be located at different distances from the temperature controller. Its information content in this case remains virtually unchanged.

Thus, these devices - both the sensor and the regulator - help create a favorable indoor microclimate by controlling the entire floor heating system.

Features and benefits of use

Installing a temperature sensor and thermostat in a heated floor system is optional. But experts strongly recommend not to neglect them. The presence of these small but important devices is necessary for proper heating operation. The fact is that the absence of a temperature sensor will not allow you to control the heating temperature of the floors, which can negatively affect the condition of the floor covering as a result of violation of operating conditions.

For example, laminate and carpet should not be used at high temperatures - the permissible heating rate for coatings is only +30 degrees. When exceeded, both laminate and carpet begin to release compounds into the atmosphere, which can have a negative impact on human health. Laminate is also prone to deformation when the lamellas are significantly overheated. If a temperature sensor is built into the system, then when a certain temperature is reached, the floor heating is turned off, and the coatings are not in any danger.

The device also helps control energy costs, which means it significantly saves money that goes towards paying utility bills.

Types of temperature sensors for heated floors

The choice of a temperature sensor that is suitable in a particular situation must be approached with all responsibility. And first you should study what types of these devices exist.

On a note! In most cases, sensors for heated floors are included with thermostats, which makes them easier to install and configure.

Table. Types of sensors for heated floors.

On a note! There are types of thermostats that are immediately equipped with two temperature sensors. It is believed that such a system is much more reliable in operation than a conventional one.

Functions and selection of thermostat

The thermostat is also a very important device that is used when installing a floor heating system. It will process the indicators that the temperature sensor transmits to it and, depending on them, control the system.

Thermostat functions:

• heating system control;
• control and maintenance of optimal floor temperature;
• process of monitoring consumed electricity;
• optimization and improvement of floor heating operation.

On a note! The energy consumption of the entire system usually corresponds to ½ of its power. In this way, approximate costs can be calculated.

Table. Types of thermostats.

Experienced craftsmen recommend installing a programmable thermostat during installation. The costs for it will quickly pay off during the heating season, when electricity bills will increase significantly compared to the warm period of the year.

There are also thermostats with a limiter. This type of device is triggered depending on the maximum/minimum permissible temperature. Its main functions are to prevent the floor from overheating or cooling down too much.

There are regulators and alarms. If the sensor detects overheating of the coating, the device will notify the home owner about the violation using a special signal.

Pros and cons of thermostats

Undoubtedly, the use of a temperature sensor and thermostat in itself is a big plus for the operation of the entire underfloor heating system.

However, each type of device has its own advantages and disadvantages.

1. Advantages electromechanical devices– versatility, ease of use, high reliability and low cost. In addition, if necessary, this type of device is easy to repair or replace yourself. The main disadvantage is the need to control the system manually. It does not respond to ambient temperature.
2. Electric thermostat(together with the sensor) is equipped with a display showing performance indicators. It also has the advantage of being able to set precise temperature values.
3. Flaws programmable thermostat– high price, difficult to operate. But some models can even be controlled using a phone or computer.

In each individual case, the most convenient thermostat can be used. For example, in order to save money, electromechanical devices can be used in the bathroom, toilet and other small rooms where a person is not present for a long time. But programmable ones are the best option for living rooms, children's rooms, and bedrooms.

Floor temperature sensor and controller - how to select and install

The choice of temperature sensor and thermostat for installation in a heated floor system should be done correctly. Here it is important to evaluate the main indicators and operating requirements.

On a note! There are types of thermostats that can record data from sensors located in two zones (rooms) at once. Sometimes it makes sense to purchase just such devices.

Selecting a heated floor sensor depending on the floor covering

Depending on the type of floor covering, certain types of sensors should be used. There are the following types of device.

1. Fits under soft surfaces(carpet, linoleum, parquet, laminate). The sensor in this case is a small cylinder attached to the end of a special cable. It is installed only after the concrete screed has completely dried, in which a small groove is then made specifically for the device.
2. Installs under hard surfaces. The larger element has a special gel shell that protects the device from shock and mechanical damage.

Installation of thermostat and sensor

Installation of these two devices is quite simple and, as a rule, even beginners do not have any problems if they act in accordance with the instructions. There are two ways to connect a temperature sensor.

1. Directly. In this case, the heating cable itself is combined in one bundle with a thermostat.
2. Using a junction box. In this case, one cable is laid from the thermostat to the junction box, and then another to the heating element.

To connect the temperature control system, you should organize a separate line from the electrical panel. Copper wiring with a cross section of 2.5 mm 2 is perfect for this. Next, a groove is cut into the wall into which the corrugations with the wire from the temperature sensor and the heating cable will be laid.

Step 1. The wire, at the end of which a temperature sensor is installed, is inserted into a corrugated tube of a suitable diameter.

Step 2. The sensor wire also comes out of the other end of the corrugation.

Step 3. The end of the tube, where the sensor itself is located, is closed with a special plastic plug. This is necessary to ensure that nothing gets there, including the construction mixture with which the system will be filled.

Step 4. The end of the tube with the sensor is fixed between the two heating circuits right in the middle. It is secured with a plastic clamp or special tape. In this case, the installation location of the sensor is selected so that it is relatively close to the thermostat itself; it is desirable that there is relatively easy access to the sensor. The optimal distance from the device to the wall is 50-60 cm.

Attention! The temperature sensor should not be located close to heating appliances or fireplaces or stoves. Otherwise, errors in the readings will be noted.

Step 5. The tube from the location of the regulator is led to the floor in a special groove. Its bend at the floor should not be sharp - at least 5 cm.

Step 6. The groove in the wall, after laying all the wires and the corrugated tube in it, is sealed with cement mortar.

Step 7 The wires must be tinned.

Step 8 After this, the wires are connected to the thermostat. The regulator is installed in its place - a hole in the wall above the groove for the wires.

Step 9 All electrical connections are checked and then the floor heating system is turned on for one minute. This will allow you to check its functionality.

Step 10 If everything works, the warning light on the thermostat panel will light up, and the floor system will also heat up. The sketched diagram of the heated floor indicates the installation location of the temperature sensor.

Replacing the temperature sensor

If the thermal sensor of the heated floor fails, it will have to be replaced. Otherwise, the thermostat will not be able to control the heating system. Diagnostics with a tester will help you find out the cause of the breakdown. As a rule, it identifies two causes of a malfunction - both of them are related to contacts (either it is present where it is not needed, or it is absent where it is needed).

The first step is to test the input wires - to do this you will have to disassemble the regulator housing. When the power supply is turned on, the tester checks for the presence of voltage in the wires. If there is no power, it means that one of the switches is not working - then the functionality of the devices in the network is checked up to the location where the regulator is installed. If there is voltage at the input contacts, then the test continues on the weekend. When the current is turned off, the thermal circuit wires are disconnected from the regulator. If in this case, when the power is turned on, there is no voltage on the output wires, then the breakdown is hidden in the control unit or in the sensor itself. The sensor resistance is checked using an ohmmeter. If the sensor does not work, it should be removed if possible and a new one installed.

Attention! The sensor cannot be repaired, it can only be replaced with a new one. In this case, you will have to buy a new regulator.

What to do if the sensor is not installed

Using a heated floor system without a temperature sensor is risky - you can ruin the floor covering. There are several ways to solve the problem.

1. Equipping the system with an air sensor (installation is possible only for a cable heating system. The power of the heating circuit must be equal to 170 W/m2).
2. Installation of the sensor in the screed (it is necessary to groove the floor with high precision so as not to damage the heating system).

During installation of a heated floor system, installing both a temperature sensor and a regulator is quite simple. It is more difficult to carry out work if the devices were neglected at one time, and then realized that they were still necessary. Fortunately, everything can be fixed.

As practice shows, most often buyers prefer to install. How is a heated floor installed in a bathroom? What do you need to know for it to work correctly and efficiently and to please you with warmth for many years?

Let's answer the most frequently asked questions regarding installation and its most popular option - cable underfloor heating in the bathroom.

The most frequently asked questions are:

1. Where and how to install the thermostat correctly?
2. Is it possible to connect a heated floor in the bathroom and in the toilet to one thermostat?
3. Actual laying area - what furniture can or cannot be laid under?
4. What indentations should be made when laying?
5. When can it be installed? heated floor under the bath?
6. What thermal insulation material is recommended to use?

Carefully read the instructions for the heated floor before installing it. In most cases, it contains detailed, well-illustrated step-by-step instructions that allow you to install the system yourself.

Installing a thermostat

Before installing underfloor heating, the first thing you need to do is choose a place to place it. thermostat. The vast majority of thermostats are not recommended for installation in the bathroom, since their protection class (IP 21) does not guarantee long-term operation in wet rooms. Therefore, the priority place for it is a corridor or other dry room. In this case, the heated floor sensor, which reads the surface temperature, is located in the bathroom.

After the location for the thermostat is selected, a hole is made in the wall at the level of its intended installation. A corrugated tube is inserted into it, into which a temperature sensor will subsequently be placed.

When installing a corrugated tube, it is necessary to observe the recommended bend radius of the tube with the horizontal floor of at least 5 cm. It is also desirable that the tube have no more than one bend. This is necessary so that if the sensor fails, it can be replaced without opening the tile.

To prevent cement mortar or water from getting inside the tube, its end is closed with a plug.

How many thermostats to use

Often, when purchasing a heated floor for the bathroom and toilet, the question arises: “is it possible to connect the heated floor in the bathroom and toilet to one thermostat?”

It is possible, but not recommended. Especially if the rooms have different temperature conditions, since the sensor reads the temperature from only one room. Depending on where the sensor is located, the floor temperature for another room may be either too high or too low.

Warm floors in the toilet and bathroom

If the temperature conditions in the bathroom and toilet are approximately the same, then you can connect two systems to one thermostat. In this case, the temperature sensor should be located in the room in which there is more heat loss and a lower floor surface temperature, and a pyrometer is used to determine the floor temperature.

It is important to note that if one thermostat is installed for two rooms, you cannot turn off each heated floor individually. It is also impossible to separately regulate the temperature in the bathroom and toilet, which in itself is inconvenient and not beneficial in terms of saving energy consumption.

Actual area of ​​underfloor heating

The next thing you need to pay attention to during installation is the actual installation area.

Warm floors are not installed under furniture without legs. In addition, their installation is carried out taking into account certain indentations: at least 10 cm from walls and stationary furniture and at least 30 cm from radiators and other heating equipment. Otherwise, the cable may overheat and fail.

Warm floor under the bath

Installation of heated floors under the bath is possible only if the bathtub stands on legs, and there is no tiled apron between it and the floor and no decorative screen is installed. When installed under an apron or screen, there is a real chance of the cable overheating at the junction of the bottom tile of the apron and the floor.

Warm floor in the bathroom under tiles

Thermal insulating material

An important point when installation of heated floors in screeds– laying heat-insulating material. In principle, any foam insulation with a thickness of at least 5 mm is allowed - for example, polyethylene foam. However, it is better to use thermal insulation with a thickness of at least 10 mm and a thermal conductivity coefficient not higher than 0.05 W/sq.m x°C.

Ideally, insulation with external heat-reflecting foil covered with a Mylar film is used, which protects the foil coating from the aggressive effects of cement mortar during its hardening.

The use of thermal insulation not only allows you to save on electricity, but also significantly increases the heating rate of heated floors.

If we compare electric and water heated floors in the bathroom, it can be noted that the installation of the first is much simpler. Therefore, by following all the instructions and recommendations, you can install a heated floor yourself, which will create comfort in your home for many years.

The floor heating system allows you to maintain a comfortable microclimate in the room, giving the owner the opportunity to independently determine the required temperature. To control the heating intensity of this type of system, they are equipped with a device known as a thermostat.

If desired, you can install the mentioned device yourself. The performer must initially prepare himself for the seriousness and responsibility of the upcoming event, while not forgetting about the safety regulations.

The system, in addition to the thermostat itself, includes a special temperature sensor. Installation of the second device is carried out using a corrugated plastic tube. This product is located in the floor screed.

Modern thermostats have the ability to be programmed, which is very convenient. For example, the owner can configure the device in such a way that, in the absence of the owners, the heated floor will operate in energy saving mode, and some time before people arrive home, it will switch to full heating mode, ensuring the desired temperature in the room being served.

Regulators with a programming function are somewhat more expensive compared to their “brothers” without this feature, however, due to savings on the consumption of the heat source, the difference in price is compensated for on average in 1-3 seasons.

Preparing for work

Before installing the temperature controller, carefully read the instructions provided by the manufacturer. The section devoted to the installation of the device itself deserves special attention, because the procedure for performing this activity differs for different models.

Thermoreg TI-200 thermostat. Instructions

Thermostat UTH-150 Euro type. Certificate and installation instructions

Remove the front panel of the regulator by carefully removing the control wheel. To do this, carefully pry the element with a screwdriver, and then unscrew the securing screw. If the regulator model you choose is equipped with latches, simply press them with a screwdriver and the panel will come off.

Important! If the cover cannot be removed, there is no need to try to solve the problem by applying mechanical force. This way you risk breaking the fasteners. As a result, you will have to buy a new regulator. It is better to carefully read the manufacturer's manual and disassemble the device in accordance with the given sequence.

Prepare the following equipment for installing the device:

• corrugated tube. In most situations, this product is included in the factory configuration. If specifically in your case the manufacturer did not equip its product with a corrugated mounting pipe, purchase it separately. A tube with a 16 mm diameter is optimal. To determine the required length, measure the space between the installation locations of the heating system regulator and the temperature sensor;
• screwdriver;
• mounting screws;
• installation box;
• level;
• indicator screwdriver. Designed to determine the voltage in the network. Can be replaced with another device with similar functions.

Nuances of installing different types of thermostats

When studying the instructions for the selected thermostat, pay attention to the service area indicated by the manufacturer. If you plan to install the device in a large room, it would be advisable to divide the space into several areas and install a different temperature controller for each of them. Otherwise, the device may simply not withstand the applied load and there will be no point in using it.

Regulators can have different designs and functionality. Depending on this, the installation procedure for the device will vary slightly. Information on this matter is given in the table.

Table. Differences in the main parameters of thermostats

Useful information about electrical wires

Several wires are inserted into the box, the insulation of which has different colors. In accordance with generally accepted provisions, a blue wire goes to zero, the phase is connected to a wire in black insulation, and grounding is provided through a wire in a yellow-green sheath.

You can find the phase using a special network indicator. Also during the preparation process you should measure the voltage level created between zero and phase. A value of 220 V is considered normal.

You must cut the wires of the main heating cable as well as the power supply. This can be done using a sharp knife or special nippers. The cables must be cut so that they extend approximately 5 cm from the installation box. The wires must be stripped. If you are installing a device with a screwless connection, information about the recommended length of this stripping will be indicated on the device body. Make sure that the stripped ends of the cables do not touch. To connect the ground wire to the heating cable braid, use soldering or a terminal.

Next, you need to connect the power wire to the thermostat you are installing. The system connection diagram is given in the manufacturer's manual or on the device body. It will differ for different devices, so check this point individually.

Connect the phase wire to the corresponding contact of the device being installed. You can find out the required contact by marking with the Latin letter L. Feed the zero cable to the terminal marked with the letter N. Be careful: there are systems on sale in which the N-terminal provides for connecting the main heating cable of the system being installed. Check the manufacturer's manual for this information before performing any work.

Connect the temperature sensor to the sensor terminals. As noted, this sensor is located in a corrugated pipe. If it is not inserted into the tube initially, you will need to do it yourself.

Key Safety Points

Any electrical installation work must be carried out in strict accordance with safety precautions. Neglect of these provisions may result in the most unfavorable consequences. The key recommendations are:

• before starting work, turn off the power to the entire apartment/house or directly to the line allocated for connecting the thermostat, if such a possibility exists;
• Do not connect a disassembled device to the mains;
• do not use the regulator at temperatures above +40 and below -5;
• do not allow the thermostat to become dusty;
• Do not use any solvents to clean the device. The use of benzene for these purposes is also unacceptable;
• do not repair the regulator without the appropriate skills;
• do not exceed the power and current values ​​specified in the manufacturer's instructions.

Step-by-step instructions for installing the regulator

The event under consideration consists of several main technological stages. Follow the given sequence, and everything will definitely work out.

First stage. Armed with a hammer drill, drill or other suitable tool, prepare a hole in the wall for the connected device. Its size should allow the box to be installed. At the same stage, arrange channels for laying cables and arranging the sensor. Place the installation box into the previously prepared mounting hole.

Corrugated wire routing diagram

Third stage. Install the temperature controller. Your task comes down to simply fixing the device in the box.

Fourth stage. Connect the main components of the system. At this stage, you must strictly follow the manufacturer's instructions, because The sequence of actions is slightly different for different device models.

Fifth stage. Install the front panel. For fixation, use the mounting screws included in the kit. Check the evenness of the regulator installation using a level. After this, close the thermostat cover and turn on the voltage. If everything is in order, you will understand this when the underfloor heating indicator lights up or the controller screen turns on. You can start setting up your device.

Important! Experts recommend putting the heated floor system into permanent use at least 3-4 weeks after pouring the screed and laying the tiles, if it was chosen as the final decorative coating. When exposed to heat, the fill may simply crack.

The performer is only allowed to measure the resistance created between the heating wires, using a tool specially designed for this. The obtained measurements are compared with the optimal values ​​given in the manufacturer's manual. If everything is in order, all that remains is to wait until the screed has completely dried and gained strength, after which the system, equipped with a thermostat and an accompanying sensor, can be put into full operation.

Good luck!

Video - Installing a heated floor thermostat

An objective look at the operation of a heated floor, the level of comfort created and the costs associated with energy consumption leaves no doubt that the heating system must be equipped with a thermostat - a device that regulates the heat supply.

Installation of a heated floor thermostat

Without connecting a device that regulates the heat supply to the floor heating system, it will function in continuous mode. The floor covering can heat up to 38 degrees. C, which creates an atmosphere in the room that is far from comfortable, and also costly. The inertia of the heating system should also be taken into account. If the heating circuit is turned off at night and turned on in the morning, both the cable and water systems simply physically will not have time to heat the floor even before the first-graders arrive from school. Therefore, in order to eliminate the occurrence of such discomfort in the house, it is worth purchasing and installing a thermostat in the underfloor heating heating system. Installation of the heated floor thermostat is carried out on the wall, in an area free from furniture and at a height of 1.2 - 1.5 m. Only for thermostats in which an air temperature sensor is installed, the recommended height from the floor is 30 cm. Based on installation technology, thermostats are divided into overhead and built-in (hidden).

A malfunction of the thermostat may occur as a result of a malfunction in the device itself or a malfunction of the temperature sensor. If, when the power is turned on, voltage is not supplied to the heating elements, then the thermostat should be diagnosed. Only a qualified electrician or a specialist in the organization of heated floors can find the cause of the breakdown, repair the thermostat parts or replace it. If the temperature sensor fails, the heating circuit will operate, but will not turn off when the set temperature is reached, which will lead to increased energy consumption. The sensor cannot be repaired; it simply needs to be replaced with a new one.

Thermostats for heated floors Legrand - a tandem of aesthetics and quality

The Legrand room thermostat has gained popularity among consumers with its laconic design, reliable functionality and reasonable price. The color of the front panel is white, titanium, ivory. Structurally, the thermostat is made for a hidden type of installation. A heated floor temperature sensor and a cable L= 3 m (4 m) are supplied with the device. The thermostat independently turns on and off the heating element when the circuit is heated to the desired temperature. The thermostat for heated floors Legrand (Germany) belongs to the group of mechanical type devices.

With rare exceptions, connection to the network of underfloor heating heating elements is carried out through a thermostat. Most manufacturing companies print an image of the thermostat connection diagram on the back surface of the device case. By connecting the device according to this diagram, the consumer will be confident that the connection is made correctly and the floor heating system will function uninterruptedly.

Connection diagram of a thermostat for a heated floor to the electrical network

The thermostat can be connected to the electrical network separately from other household appliances using an electrical panel, or it can be done directly, that is, simply plugged into a household outlet. When connected separately, to turn the thermostat on/off and to protect against power surges in the network, a circuit breaker is installed. When connecting the thermostat to an outlet, it is important to consider the power of other devices that are connected to this outlet.

The heated floor is connected to the thermostat via a temperature sensor. The temperature sensor should be located under the infrared heating tape or between the heating cable lines. The sensor itself is placed in a corrugated PVC pipe with a diameter of 16 mm. At the floor-wall transition, the bending radius of the tube should be as large as possible so that the sensor cable is not pinched and is located freely in the pipe. It is necessary to prevent moisture from entering the tube, so its end should be plugged. Correct placement of the sensor ensures easy installation and, if necessary, comfortable removal of the sensor.

The consumer decides which thermostat to choose for heated floors

The industry produces three types of thermostats: manual (mechanical), electronic and programmable. The cost of a manually controlled thermostat is low, and operation is simple. By rotating the built-in element simulating a wheel, the consumer sets the digital value of the desired floor temperature.

An external distinctive feature of electronic thermostats is the presence of an LCD display. The device is controlled using buttons located on the front panel. These devices have a high level of accuracy in adjusting the heating process, but are more dependent on the quality parameters of the supplied electricity.

Program-controlled thermostats “manage” the operation of the heating system in autonomous mode. The consumer can put into the device a set of all the desired parameters of the system’s operating mode - the number of hours of operation during the day, the time of day, and even the days of the week.

Thermostat for heated floors: which one to choose?

How to choose a thermostat for a heated floor so as not to make a mistake

When selecting a thermostat model, one must proceed from the fact that a reliable thermostat must not only turn the floor heating circuit on and off, but also have a power that is 15% greater than the system power and ensure that the specified temperature is maintained on the floor surface. It is not recommended to purchase a thermostat for a heated floor with sensors that indicate the air temperature in the room, since the indicators are distorted by external factors: warm or cold air streams from household appliances or banal drafts.

How to connect a heated floor to a thermostat diagram

The manufacturer places a diagram for connecting the heated floor to the thermostat: on the thermostat body, on the packaging, or in the instructions attached to the model. The sensor, placed in a plastic corrugated tube, is placed between cable threads or under an infrared heating film. In the thermostat, the wires from the sensor are connected to two contacts marked in the form of the letter C. Then the wires of the floor heating system are connected to the thermostat. Connect the neutral, phase and ground wires to the corresponding contacts of the thermostat marked N, L, PE.

Household thermostats are a convenient solution for competent and safe operation of a heated floor heating system, which is characterized by ease of installation, long service life and savings on energy costs.

Most often, heated floors in apartments are installed in the bathroom area. That is why potential buyers are very interested in how heating equipment is installed in this room? What parameters must be taken into account to ensure that the underfloor heating system operates correctly and efficiently over a long period of time?

We will consider specific questions and give answers and recommendations that must be followed during installation work on laying heated cable floors in the bathroom:

• How and where is it best to install a thermostat?
• Is it possible to connect the heated floor in the toilet and bathroom to one thermostat or is it necessary to use two devices?
• Under what types of furniture can or cannot underfloor heating be installed (actual installation area)?
• Are indentations necessary when installing heated floors and what kind?
• In what cases can a heated floor be installed directly under the bathtub?
• Thermal insulator (recommendations for use)?

Warm floor in the bathroom

Before installing a heated floor, it is very important to carefully study the instructions supplied with it. As a rule, it contains detailed, step-by-step instructions with colorful illustrations, thanks to which even an amateur can install the equipment at a professional level.

Installing a thermostat

First of all, even before installing a heated floor, you need to choose a location for the thermostat. Manufacturers of these devices do not recommend placing them directly in bathrooms, since their protection class - IP 21 - guarantees long-term operation in rooms with high air humidity. This fact cannot be discounted under any circumstances, so it is better to find a place in the hallway for the thermostat in advance. In this case, the underfloor heating sensor, which records the surface heating temperature, must be located inside the bathroom.

When the location of the thermostat is clearly defined, you need to make a hole in the wall at the level of the planned installation and insert a corrugated pipe into it, in which the heated floor temperature sensor will then be placed.

When installing a corrugated tube, it is very important to observe the recommended degree of bend of the tube with the floor horizontal of at least 5 cm. In addition, it is highly desirable that the tube have only one bend. These conditions are necessary so that if the sensor breaks down, it can be replaced without opening the tiled floor covering. In addition, the end of the corrugated tube must be closed with a plug. This will protect the inner space of the tube from the ingress of cement mortar and water, and will also protect the floor temperature sensor itself from possible damage.

How many thermostats to use

When installing heated floors in the bathroom and toilet at the same time, clients ask a completely logical question: “Is it possible to connect both systems to one thermoregulatory device?”

Experts answer that it is possible, but not recommended. This is especially true for rooms with different temperature conditions. The fact is that the sensor always reads the temperature from only one room, so there is a high probability that the temperature of the heated floors will be either excessively high or, conversely, unreasonably low, depending on where exactly the floor temperature sensor is located. If the device is placed in a cooler room, it will overheat, and if it is placed in a warmer room, it will underheat.

If both rooms maintain approximately the same temperature conditions, then connecting two heating systems to one thermostat is considered acceptable. However, for correct heating, the floor temperature sensor will have to be installed where the level of heat loss is higher and the temperature on the floor surface is lower. You can measure the floor temperature using a pyrometer.

When one thermostat controls the operation of systems in two different rooms, the user does not have the ability to turn off each heated floor separately and separately regulate the heating temperature in these rooms. In addition to inconvenience, this entails excessive energy consumption and, as a result, increased utility costs.

Actual area of ​​underfloor heating

When installing a heated floor, it is very important to take into account the actual installation area. Keep in mind that heating equipment is not installed under furniture without legs and requires a mandatory distance of at least 10 cm from stationary furniture and walls, and from radiators and other heating equipment - at least 30 cm. These rules must be followed. Ignoring the indents can lead to overheating of the cable and failure of the entire system.

Installing heated floors under the bath

A heated floor can be installed under a bathtub only if the bathtub is on legs and there is no decorative screen or tile apron between it and the floor. If a screen or apron is still present, then installing heating equipment under it can lead to overheating of the electrical cable at the junction of the floor and the bottom tile of the apron.

Thermal insulator

When installing a heating system in a bathroom, we must not forget that heated floor technology involves laying a heat insulator only when laying the cable in a concrete-cement screed. In this case, almost any type of foam insulator with a thickness of at least 5 mm, for example polyethylene foam, would be appropriate. However, to achieve a greater effect, it is recommended to take a material with a thickness of at least 10 mm and a thermal conductivity coefficient no higher than 0.05 W/sq.m x°C.

The ideal option for a high-quality and reliable insulator is considered to be a material that has a layer of heat-reflecting foil on the outside, covered with a Mylar film, which reliably protects the outer coating from the effects of cement mortar during its hardening.

The use of a heat insulator makes it possible to save on electricity bills and significantly increase the heating rate of heated floors.

Compared to other floor heating systems, such as water ones, installation of cable equipment is much simpler and more affordable. By following the instructions and recommendations set out in this article, you can install the system yourself and for many years enjoy the comfortable warmth and cozy atmosphere that reigns in your home.
